PAJU, South Korea

Dozens of South Korean workers returned from a jointly run factory park in North Korea on Saturday as part of an evacuation of the flagship project following months of military tensions.
The move plunges into doubt the future of the Kaesong complex - once a rare symbol of cooperation across the world’s most heavily militarised border, and a crucial source of hard currency for Kim Jong-Un’s isolated nation.
The workers’ return came on the same day that the North announced it would put a Korean-American arrested in November on trial for trying to overthrow the communist regime - a move sure to add to frictions with the West.
Seoul said Friday that it had decided to pull all remaining employees from Kaesong after Pyongyang rejected its ultimatum to join formal negotiations on restarting the stalled operations.
A total of 126 people, including one Chinese national, returned on Saturday through a border checkpoint in Paju in dozens of vehicles loaded with assembled goods and other materials salvaged from the complex. “I feel more worried than relieved being back home for the first time in a month,” Cho Yong-Joo, a manager for a Seoul electronics firm, told AFP after crossing the tense frontier. “Kaesong ought to survive but things are not good,” he said.
Some of the workers burst into tears when reunited with colleagues waiting to welcome them home. The roughly 50 people remaining at the industrial zone - mostly government employees who manage the site as well as telecom and electrical engineers - are expected to be pulled out on Monday, according to Seoul.
North Korea said Saturday that it would put a US citizen on trial for trying to overthrow the communist regime, in the face of soaring tensions between Pyongyang and the West.
The North’s official Korean Central News Agency (KCNA) said Pae Jun-Ho had admitted to the charges and would soon face “judgment”.
The announcement follows a months-long standoff on the Korean peninsula stoked by the North’s nuclear test in February, which prompted the UN Security Council to impose fresh sanctions on the isolated nation.
Pae, who is believed to be a Korean-American tour operator, was arrested in November as he entered the northeastern port city of Rason.
KCNA said a “preliminary inquiry” had been completed.
“He admitted that he committed crimes aimed to topple the DPRK (Democratic People’s Republic of Korea) with hostility toward it. His crimes were proved by evidence.
“He will soon be taken to the Supreme Court of the DPRK to face judgment,” according to the report, which did not say what the charges were based on.
Seoul-based activist Do Hee-Yoon told AFP that he suspected Pae was arrested because he had taken photographs of emaciated children in North Korea as part of efforts to appeal for more outside aid for them.
The North’s announcement came hours before US Deputy Secretary of State William Burns met South Korean Foreign Minister Yun Byung-Se for talks in Seoul. The US diplomat did not publicly comment on the trial.
Several Americans have been held in North Korea in recent years.
In 2011, a US delegation led by Robert King, the US special envoy for human rights and humanitarian issues, secured the release of Eddie Jun Yong-Su, a California-based businessman, who had been detained for apparent missionary activities.
In 2010, former US president Jimmy Carter won plaudits when he negotiated the release of American national Aijalon Mahli Gomes, sentenced to eight years of hard labour for illegally crossing into the North from China.
On another mercy mission a year earlier in 2009, former president Bill Clinton won the release of US television journalists Laura Ling and Euna Lee, jailed after wandering across the North Korean border with China.
Relations between the two Koreas have worsened markedly in recent months, with Seoul announcing on Friday a complete withdrawal from a jointly run industrial park in the North after Pyongyang rejected its ultimatum to join formal negotiations on restarting the stalled operations.
The move plunged into doubt the future of the Kaesong complex - once a rare symbol of cooperation across the world’s most heavily militarised border, and a crucial source of hard currency for Kim Jong-Un’s isolated regime.
A total of 126 workers from the site returned to South Korea on Saturday in dozens of vehicles loaded with assembled goods and other materials.
The roughly 50 people remaining - mostly government employees who manage the site as well as telecom and electrical engineers - are expected to be pulled out on Monday.
South Korean companies with factories in Kaesong have expressed shock at the abrupt withdrawal.
“We’re dismayed at the sudden government decision to pull out of Kaesong. We’re concerned this would eventually result in its closure,” a representative of the 123 South Korean firms with interests there told reporters.
Established in 2004, the complex lies 10 kilometres (six miles) inside the North, which remains technically at war with the South after the 1950-53 Korean War was concluded with a ceasefire rather than a peace treaty.
